Why is ice more slippery to walk on when the temperature is 0 degrees Celsius than when the temperature is -10 degrees Celsius?

∙ 13y agoIce is not a particularly "slippery" substance. Its crystalline structure supports a friction coefficient equal to that of many types of rock. But when ice is hovering around its conversion temperature -- 0 deg. C -- it becomes a combination of things that is quite "slippery" indeed.
At exactly 0 deg. C, water is in transition, and can easily slide one way or the other, depending on input. Ice at 0 deg. C melts instantly when touched by, say, a boot that carries a temperature of 10 deg. C. The water thus formed fills the pores of the ice surface and creates a very "slippery" surface.
At -10 deg. C, this process is less likely to take place, and the ice is more likely to retain its crystalline structure and its surface roughness.

What is the temperature of the center of the eath?
the temperature at the inner core of the earth is at the high is about 7,000 degrees Celsius.(not more!)According to my calculations (and my science book) the center of the earth is about 5000 Celsius The temperature of the center of the earth is around 12,600 degrees Fahrenheit.The temperature at the centre of the earth is approximately 7,000 degrees celsius :)about 4500 degrees Celsius
Metric units for measuring temperature?
Celsius or KelvinThe metric unit for temperature is the Kelvin (symbol: K), which is defined as 1/273.16 of the temperature difference between absolute zero and the triple point of water. The Kelvin (not degrees Kelvin) is mainly used in scientific fields.The degree Celsius (symbol: °C, formerly known as degrees centigrade) is of the same magnitude, but the zero is at 273.15 K. It is more commonly used than Kelvin for everyday usage, for example in weather forecasts and room temperature. It is not the official metric unit of temperature, but is accepted for use with the metric system due its close links with the Kelvin.Read more: What_is_the_metric_unit_for_temperature
Do you write ' two degrees Celsius ' or ' two degree Celsius '?
You write 'two degrees Celsius'. If you have more than one, "degrees" is plural.
Temperature of Rigel?
There is more than one star in the Rigel "system". The main star, in terms of brightness, is Rigel A. That has a surface temperature of about 12,000 degrees Celsius.

At what temperature is Fahrenheit double Celsius?
At approximately -12.3 °F the equivalent temperature in Celsius is -24.6 °C. This is the only temperature at which the value of the temperature in Celsius is double that of the equivalent Fahrenheit temperature. To be more precise, the temperatures are -12 4/13 °F and -24 8/13 °C.

What planet drops 600 degrees every day?
Mercury, the closest planet to the sun, fluctuates in temperature more than any other planet. During the day, its temperature can reach 800 degrees Fahrenheit (430 degrees Celsius), and during the night, its temperature can drop to -280 degrees Fahrenheit (-170 degrees Celsius). This is a drop of about 1,080 degrees Fahrenheit (600 degrees Celsius).

Si unit temperature?
The SI unit of temperature is Kelvin, but degrees Celsius is a derived SI unit for temperature and more commonly used.
Does the degree symbol go before or after celsius?
It depends on what you're trying to say. If you're saying a temperature or a range, you write the degree symbol first; however, if you're saying a difference in temperature, you write the Celsius first and then the degrees. This is why- Describing a temperature involves a state of being, whereas a the difference in temperature is a comparison. Consider just writing it out: degrees Celsius or Celsius degrees. Celsius degrees sounds more like countable units because the noun (degrees) is at the end. On the other hand, degrees Celsius sounds more of a singular state. A range might give you the impression of a comparison, but it's really just two singular states. Sorry I'm rushing through this, I have a paper to do.
